Ruby on Rails Sandbox

A ready-to-code Ruby on Rails environment with everything pre-installed — no setup, no internet required. Comes with a working Rails application template, SQLite database, authentication (Devise), pagination (Kaminari), and a full RSpec testing stack (FactoryBot, Faker, Shoulda-Matchers). Write models, controllers, and views, run migrations, test with RSpec, and explore Rails conventions — all from the browser.
